According to the French Youtube video, the Crit Air certificate should be positioned in the bottom right of the windscreen. I'm assuming from the video that this is the RHS looking out from the drivers seat - in other words on the passenger side for a LHD vehicle. But looking at Google, there are also mentions of this being a MoT failure in the UK, suggestions that it should be on the passenger side (so left when looking out for a UK vehicle), and even top rather than bottom of the screen.
